Hello Ana,
here are some of the new HREAP now rebranded Flex Connect enhancements.
FlexConnect Efficient AP Upgrade
A FlexConnect Efficient AP upgrade feature enables administrators to effectively perform AP upgrades. With this feature, one FlexConnect AP of a particular model per branch office acts as a master and downloads the image from a controller, other APs of the same model in the branch pre-download the AP image from the master.
With this feature you enable local distribution of software images from the master to other APs in a branch which speeds up the upgrade and minimizes traffic over the WAN.
FlexConnect ACLs
You can filter client traffic that is locally switched on the FlexConnect access point which enables protection and integrity of locally switched data traffic at the FlexConnect access point.
FlexConnect AAA Override
This feature allows you to dynamically assign VLANs for locally switched clients on a FlexConnect access point.
FlexConnect-Fast Roaming for Voice Clients in a FlexConnect Group
This feature removes WAN link dependency by handling mobility events at the FlexConnect access points.
FlexConnect Peer-to-Peer Blocking
With this feature, you can block peer-to-peer communication on the WLAN which limits vulnerabilities from insecure peer-to-peer client communication.
